What do you mean by "fdesign generated routine"? A routine generating
the object or routine initializing it?
BTW, the simplest way I can imagine to do it is something like:
FL_OBJECT *ob;
ob = myform->first;
while ( ob ) {
ob->u_ldata = 0;
ob = ob->next;
}
Is there a better way?

Well, I agree that to be 111% sure, one should initialize it himself.
Still, it would be nice if the library would do it for the user
*officially* (i.e. with appropriate statement in the manual). After all,
you do not activate all your form's buttons by hand, do you? You
probably presume that they are active by default.
